#772: LASzip is missing in lastools (e.g. las2las, lasinfo) in OSGeo4W Shell

 ''(First issue submission was here
 https://github.com/qgis/QGIS/issues/51193 - now moved to the right pace
 here)''

 When running e.g. lasinfo or las2las in cmd-line / OSGeo4W Shell the
 following error occurs:

     error: Compression support not enabled in liblas configuration


 == Observations / Notes:

 I think LASzip is missing in the packaging/compliling.

 Running lasinfo or las2las in the cmd-line without params to show version
 header reveals:

     lasinfo (libLAS 1.8.1 with GeoTIFF 1.4.2)

 I expected:

     lasinfo (libLAS 1.8.1 with GeoTIFF 1.4.2, LASzip n.n.n.)

 What's also worth noting is that in bin (C:\Program Files\QGIS
 3.22.13\bin), there is laszip3.dll but no laszip.dll. Renaming doesn't
 help.

 == Steps to reproduce the issue

 Using QGIS 3.22.13 LTR or 3.28.1 (on Windows 11):

 1. Go to https://wheregroup.com/blog/details/visualisierung-und-
 manipulation-von-lidar-daten-mit-qgis-und-pdal/ and download the "LIDAR
 Testdaten aus OpeGeoData.NRW", unpack.
 2. Open OSGeo4W Shell and type "las2las" --> Check the header
 3. Paste the following into the command line:
 lasinfo 3dm_32_510_5704_1_nw.laz \\
 las2las 3dm_32_510_5704_1_nw.laz --output out.laz --extent "510100 5703500
 510900 5704500"
